Title: Quick-set exterior coatings
Inventor: CI XIAOHONG
IPC: C09D7/12
Filed: 1993-10-15
Abstract: ABSTRACT OF THE DISCLOSURE:       This invention solves the problems encountered with conventional exterior coating compositions by providing an aqueous, exterior, quick-set coating composition having early washout resistance and dirt pick-up resistance. The invention is particularly useful as a binder used in a traffic paint and as a base coat and/or top coat in exterior insulation finishing systems. This invention also provides a method for improving the early washout resistance and dirt pick-up resistance of an aqueous, exterior, quick-set coating.       The aqueous, exterior, quick-set coating composition of this invention requires four components: (1)  a film forming latex polymer having anionic character; (2)  an amine-containing polymer formed from at least 20% by weight monomer containing amine functional groups; (3)  a volatile base; and (4)  a water-soluble or water-dispersible multivalent metal.       The method of improving the early washout resistance and dirt pick-up resistance of an aqueous, exterior, quick-set coating involves: (1) forming an coating composition containing:     (a) an anionically stabilized latex polymer; (b) an amine-containing polymer; (c) a volatile base; and (d) a water-soluble or water-dispersible multivalent metal;     and (2) applying the coating to a substrate.

Title: Circuit for Accurately Measuring Phase Relationship of BPSK Signals
Inventor: SKUDERA WILLIAM J JR
IPC: G01S3/04
Filed: 1993-10-21
Abstract: The disclosed system measures the phase relationship of first and second BPSK signals received at a pair of receiving antennas.  The antennas are connected to respective first and second converting circuits which convert the received signals into first and second CW signals.  Each CW signal is subjected to chirp-Z processing so as to convert the first and second CW signals into first and second chirp-Z transforms, which are narrow pulses.  Then, the phase relationship of the first and second narrow pulses is detected, so as to thereby detect the phase relationship of the first and second received BPSK signals.  That phase information can be used, for example, to calculate the angle-of-arrival (AOA) of the received BPSK signals.  Advantageously, each converting circuit includes a series connection of a frequency-doubling circuit, a bandpass filter, and a circuit for dividing frequency by two, in that order.  A switching arrangement is provided which is operable for applying the outputs of the converting circuits to the phase detecting circuit only when the received signals are BPSK signals.

Abstract: A proportioning module for automatically changing the ratio of delivery pressure to control pressure according to whether a mode control pressure is present or absent. When the mode control pressure is present, the proportioning module is deactivated, causing the delivery pressure to be substantially equivalent to control pressure.   When the mode control pressure is absent, the proportioning module functions to provide control pressure to delivery pressure ratios which are dependant upon the control pressure and the resultant delivery pressure.

Title: Method of automatically approximating a function
Inventor: SCHAPIRE ROBERT E
IPC: G06F17/17
Filed: 1994-06-22
Abstract: Abstract A method for finding a result function which is an approximation or an equivalent of a target function. The method derives a hypothesis function from a set of examples which are consistent with the target function. An equivalence oracle is then used to test the hypothesis function. If the equivalence oracle indicates that the hypothesis function is equivalent, the method terminates; if the function is not equivalent, the equivalence oracle returns a counterexample with which the target function but not the hypothesis function is consistent. The counterexample is used to modify the set of examples and a new hypothesis function is derived from the modified set of examples and tested as described above. The modification of the set of examples is done using a membership oracle, which takes a value from the target function's range and returns the value of the target function on that value. Efficiency is increased by use of a greedy technique involving the meet operation to add examples to the set of examples. The method is applied to functions expressed as polynomials on Boolean variables, but may be applied to functions expressed generally as multilinear polynomials.
